My first goose season ended today. Learned a lot but my gun needs a deep clean, lots of mud this year due to high temps.

The bps is notoriously hard to reassemble. Any ideas how to flush mud out of my action without taking the gun down too far?

When I was 16 I took it all the way apart and couldn't get it back together after a dove hunt in the rain. Had to drive it to the factory. The manual says to not take it apart further than barrel removal. Obviously that won't let me remove dirt and feathers from the action.


Thanks
 
I've always had a fairly high mechanical aptitude. But, if you don't or have a gun designed by Rube Goldberg, you can use an arisol solvent. While spraying let gravity move the grit away from the trigger. If you use this method make sure your solvent wont dissolve plastic parts or finishes.

Gramps sprayed ether in his .22lr auto. When the drippins run clear let it dry and relube. Ether works well as it removes all lube and grit and dries fast. I don't think at will help with mud or feathers....
 
The only issue is getting the shell stops back in after you pull the trigger group. If you get a couple of pieces of 0.002" shim stock you can shoehorn everything right back in. I used to take mine down ALL THE WAY once a year after waterfowl season, or if we took a bath.
 
just flush it out and let it dry then give it a touch of lube....if you want, remove the stock first then you don't have to worry about the finish,.....
 
There's literally mud and feathers in the gun, I don't think flushing it out will work. I remember getting it apart ok but having issues mentioned above. Could get the trigger group in while keeping everything in place.

Guess I'll open it up tomorrow. I don't trust any gunsmiths around here, figure I'll take it apart and clean it. Worst comes to worst it'll probably be cheaper to have browning put it back together after the pieces are clean.

Last time they charged me $60 or so but refinished the gun without asking me!!! That was 10 years ago. BPS is no 870 but I shoot them way better and the express these days are pretty rough.
 
If it were mine, I would remove all of the wood and soak all of the remainder in mineral spirits in a plastic trough. Let sit for a day or two and let gravity do some of your work. I would then hose down with non-chlorinated brake cleaner and re-lubricate. Re-install the wood and you should be good to go.
 
Just wondering aloud. I used to get very high round counts with handguns and stripped the stocks off and flush them with naphtha. Would that work, or is there some parts that wouldn't take kindly to it?
 
As mentioned try U-Tube. Should be a tutorial on the subject .Tear down and re-assembly of that model shotgun. Audio/video. Other than Brownell`s.
 
I don't think soaking or flushing with an aerosol will work, there is solid organic matter in the gun. I don't have wifi and my service isn't good enough on my phone for video. Figured some of you guys had been down that road.

This is the route I'm taking. Would be interested to see the trick they use at the factory, I'm sure it's easy when you do it all day. Going to load some 38s then start disassembling the jigsaw puzzle. I just remember it being way more difficult than any other gun I've torn down including Hi Powers and other older designs.

Always pains me that some consider assembling an AR as "gunsmithing". Thats why I don't trust most "gunsmiths" outside the few I know that have the patience
 
Just throwing this out there. I enjoy motorcycles. Kerosene makes short work on greasy metal parts like chains. I've used it with success on receivers and internals gun parts taking care not to get it on wood or plastic. I believe WD-40 is largely aeriated kerosene.

Also, are there inexpensive ultrasonic cleaners out there? It would be nice to drop in assemblies like trigger groups.

BPS? I would say take plastic/wood parts off use water hose or hot water flush and dry in kitchen oven. Not sure what temperature you would set oven to.:confused:
 
Youtube has a few videos detailing the disassembly and reassembly. Just type Browning BPS into the youtube search bar . I've owned a BPS since the 80's.They are a bit tedious to reassemble.

Pardon my ignorance, but what do you with the shim stock? Do you maybe make a V-shaped spring or U-channel spacer to keep the two stops pressed into the receiver?
